, iMPn'ovEMENT in PLANES.

The Schedule referred to inthese Lettexs'Patent and making` part of the same.

Beit known that 1, 'TIMOTHY O. CALLAnAs, of Boston, in the'county of Suffolk and State of Massa- `chusetts,lhave made an invention of a new and useful Plane for Finishing Board Floors of Halls, Dwellings, `ITavigable Vessels, &c.; and` do herebydeclare the 'following to be a full, clear, and exact description thereof, due reference being had to the accompanying drawing making part-of this'specitication, and in which- Figure 1` isa perspectiivc view; and Eigurel, a vertical, central, and longitudinal section of ai .plane embodying my improvements.

i 4'.lhe stcoping or orom'shiugposition now assumed, of necessity, by carpenters in planing or finishing board` floors,.and the time consumed inV the act, have ren- `d ered the introduction-ot' an implement similar to that .lherein -explained-of---grcatvalne,thc object to be accomplished being `the `construction of a plane that may be' operated by acarpentcr or laborer while in an ordinary erect walking position, the `result being `great economy of` time, as' well lcssening of fatigue on `the part of Athe operator.

The invention consists-' Y First, inmounting a carpcntcrsl plane upon wheels `or rollers,- or a carriage supported upon wheels or rollers, in such manner that said plane may `bc easily Secondly, in providing arcarpcntes plane with an attenuated slopingr handle, rising therefrom to such a height as to enable a person to readily grasp it, while in a 'standing position.

In the drawing which accompanies and constitutes part of this specification- A representsa carpentelis plane, the for-ward end v of which'-. is mounted uponwhcels or rollers, I; b, in order that it may be easily propelled along the floor, thc rollcrs'or their equivalents 'being of considerable weight, inox-der to insure the contact of the. plane with the floor. '1 w The iron of the plane is shown at c` as confined within thethroat o'r sha\-'iiig-pas sage 1l of the plane, in part, by as'crew, e, which passes through a slot, f, ibrmedcentrallyiu the plane-iron, and screws into the rear wallof the 'throat d, and serves to"Lclamp the iron The verticaladjustment of tlieplane-iron is cii`ectcd by a long screw,.g,` which screws through a stud, 7i,

` connected to the rcar side of the planc-iron,-'aml at or "near thc upper part thereof, the lower end of the screw y. being swiveledto a metallic plate, i', which is secured to the upper part of the plane, and in rear of its iron, the opposite or upper end of the screw being provided with a milled head, or its equivalent, by which it may be easily rotated. i Y

propelled over the surface of a floor, while. at work and van The plane-iron e is not connected rigidly or immovably to the stud h before mentioned, but merely encompasses the same, consequently, by`looscning -the screw d, which clamps the iron to the plane, such n'on may be instantly removed therefrom, free from any incumbrance. y

As before observed, the head of the screw y rises Ito such a position as to he readily seized by a workman while standing erect, or substantially so.

K in thc drawing denotes au attenuated handle at tached toI the' rear end of thc plane A, amlrising therefrom at au oblique angle in parallelism, or there about, with the screw g, which it should slightly ovcrtop, and to such a height as will enable the workman, by its aid, to propelt-he plane over the surface of a iioor in an ordinary walking position, with results and advantages before premised.

l-lnu'chertcfore stated .that the wlmels b should possess sufficient gravity to maintain the plane in Contact with thc floor against irregular movements on the part of the workman, and I would here state that y it and the oor is greatly reduced, in addition to its prolonged handle.

As the wheels b or their equivalents are the only points of. support or contact necessarily of the plane with respect to the iioor, it results that thc lower surface ofthc plane, from its throat rearward, may be .sloping or curyed, shouldsuch form, from any reason,

be found necessary.

Thoulnerits of'a plane provided with a means oi propulsion, as before stated, will be at once apparent Ito persons whose, occupation, like my own, is that of planing floors.

The relief from the strain and unnatural position now, of necessity assumed, and the case and rapidity with which a Hoor may be plaucd by means of my ir.- vention need no further comment.

A carpenter-s plane, when providial 'with wheels o1 rollers and an elongated llaiidlei, all constructed in the manner and for the purpose herein specified.
